Description

Alignment system for cleat and base assembly

The present invention relates generally to an alignment system for a cleat and a base assembly, and more particularly, to an alignment system for promoting a blind engagement between a cleat and a pedal assembly. .

Footwear mounting engagement methods have been used in bicycling, skiing, snowboarding, rowing, and many other sports to attach a user to a device for increased power and / or control.

In particular, engaging shoe-mounting cleats to bicycle pedals has been known to be difficult for several reasons. The cleat is mounted to the underside of the sole of a cyclist and is therefore hidden from view. Similarly, the pedal assembly mounted to the underside of the rider's sole is also hidden from view due to the shoe during the engagement procedure. Therefore, engaging a cyclist's shoe to a pedal assembly requires the cyclist to blindly align or engage the cleat to the pedal, which mainly relies on tactile feedback and is most common when the cyclist is still in motion.

What exacerbates the difficulty of engagement is that the bicycle pedal is rarely in a fixed position and rotates freely on the crank, and these cranks also rotate freely on the bicycle. Looking down at the general tendency of pedals to promote meshing is both inconvenient and dangerous because it distracts the rider from paying attention to the road or trail and can cause the rider to shake or hit a fixed object while passing.

In recent years, other factors have increased the difficulty of engaging footwear mounting tabs to the pedals. For example, many pedals and clasps have become smaller and smaller over the years, and this makes It becomes significantly more difficult to align the slice to the target area of the pedal.

Therefore, there is a need for a modified cleat and pedal assembly that permits a blind engagement between the pedal and the cleat that does not require precise alignment of the two components to promote engagement.

Various embodiments of a cleat and pedal assembly are described herein, and these embodiments provide reliable and easy engagement and release of the cleat and pedal assembly. Cassette pedals, and in particular cassette pedals made for off-road use, are generally designed with relatively small cleat components mounted in a small recessed cavity that is usually constructed into the sole of a shoe. Since the cleats are relatively small and are placed on the bottom side of a user's shoe, when the cleat contacts the pedal, it only relies on tactile feedback to blindly perform the alignment and engagement of the cleat to the pedal. .

In one embodiment, an alignment system is provided for facilitating engagement of a cleat to a base assembly. The alignment system includes a forward cleat edge and a rear cleat edge, and a pair of guides, the pair of guides are formed from opposite sides of one of the forward cleat edge or the rear cleat edge.

Turning now to the parts of the buckle assembly 100 and the base assembly 200 that cooperate with each other, the buckle assembly 100 includes a plastic shape and a configuration that are respectively releasably fixed to the base edge before the base edge 212 And one of the forward buckle edge 112 and a backward buckle edge 114 within the rearward base edge 214. In a preferred embodiment, one or both of the forward-facing base edge 212 and the rear-facing base edge 214 are spring biasably retractable toward each other.

In a preferred embodiment, both the forward tab edge 112 and the rear tab edge 114 define a region or a recess that holds the forward base edge 212 and the rear base edge 214, respectively. To this end, the forward base edge 212 and the rear base edge 214 may be shaped into a warp or a tongue to closely match the forward flap edge 112 and the backward flap edge 114. .

Once the forward tab edge 112 and the rear tab edge 114 are coupled to the forward base edge 212 and the rear base edge 214, respectively, the forward base edge 212 and the rear base edge 214 are separated from the respective forward directions. The tab edge 112 and the lateral contacts 118 on the opposite sides of the rearward tab edge 114 are in close contact. Although the cleat assembly 100 is shown as including lateral contacts 118 on opposite sides of both the forward clasp edge 112 and the rear clasp edge 114, it should be understood that the lateral contacts 118 may be provided only for the forward clasp. One of the sheet edge 112 and the rearward tab edge 114.

As shown in FIGS. 9 to 10, the forward flap edge 112 is positioned close to the toe region 14 of the shoe 10 and the backward flap edge 114 is positioned close to the heel region 16 of the shoe 10. Therefore, the forward flap edge 112 and the rearward flap edge 114 are positioned apart along a longitudinal axis A-A of the shoe 10 by a distance.

The guide 116 may be provided to extend laterally outwardly from the opposite side of either or both of the forward flap edge 112 and the rearward flap edge 114 to facilitate separation from the forward base edge 212 and the rearward base, respectively. The alignment and engagement of the seat edge 214. In a preferred embodiment, the guide 116 extends laterally outward from the side opposite to the edge of the clasp that first engages the base assembly 200. In this In the preferred embodiment of the buckle assembly described herein, the forward buckle edge 112 provides initial engagement with the base assembly 200 and therefore the guide 116 is shown as being provided in conjunction with the forward buckle edge 112.

The guides 116 each include a proximal end that is adjacent to the outer side of the forward buckle edge 112, is coupled to the outer side of the forward buckle edge 112, or is integral with the outer side of the forward buckle edge 112, and is far away from the buckle body 110. A distal end 117. In a preferred embodiment, the guide 116 is between 95 degrees and 180 degrees, preferably between 120 degrees and 155 degrees, and more preferably between the opposite sides of the forward flap edge 112. An angle θ between 130 and 145 degrees extends laterally. One function of the guide 116 is to substantially increase the size of the landing area 12 or "target area" of the shoe, so that substantially less accuracy is required to align the forward flap edge 112 with the forward base edge 212 to Used for meshing. Therefore, the guide 116 effectively complements a larger area of the sole during the engagement procedure.

FIG. 9 shows the guide 116 as a part of the structure of the cleat assembly 100 or is integral with the structure of the cleat assembly 100, and FIG. 10 illustrates a separation from the cleat assembly 100 and instead of the shoe 20 The structure of the sole is an integral guide 22. It should be understood that there may be a gap between the guide 22 and the forward buckle edge 112 as long as the gap is smaller than the width of the forward base edge 212 so that the gap does not "clamp" the forward base edge 212 . It should be understood that any of the configurations shown in FIGS. 9 and 10 may be used as long as the proximal end of the guide is at the opposite outer side of the forward flap edge 112 or adjacent to the forward flap edge 112 Terminate on the opposite side.

In the embodiments shown in FIG. 1 to FIG. 4 and FIG. 9, it should be understood that the guide 116 is directly mounted on the sole. In a preferred embodiment, the bottom surface of the guide is installed to be substantially flush with the bottom side of the sole of the shoe, as shown in FIG. 9. In a particularly preferred embodiment, the distance between the bottom surface of the guide and the bottom side of the sole is not more than 2 mm.

Referring now to both FIGS. 9 and 10, a landing area 12 is generally defined on the bottom side of the sole in front of the cleat edge 112 and between the guides 116. In a preferred embodiment, the landing area 12 has a substantially frustum that has an enlarged width that is open towards the toe area 14 of the shoe. Cone shape. This landing area 12 provides a significantly larger area of contact between the bottom side of the shoe 10 and the forward base edge 212 that still allow the alignment and engagement of the forward flap edge 112 and the forward base edge 212. This is better understood with reference to FIGS. 6 to 8.

6 to 8 illustrate a sequence of engaging the clasp assembly 100 to the base assembly 200 in a releasable manner. It should be understood that in order to more clearly illustrate the order of aligning and engaging the cleat assembly 100 to the base assembly 200, the shoes to which the clasp assembly 100 is mounted are omitted.

FIG. 6A to FIG. 6C illustrate the engagement of the forward facing flap edge 112 and the forward base edge 212 as facilitated by the guide 116. This initial engagement between the cleat assembly 100 and the base assembly 200 is usually the most difficult because the user needs to blindly align the forward clasp edge 112 and the forward base edge 212 and rely only on the sense of touch Give feedback. To this end, the guide 116 cooperates with the bottom side of the sole to which it is mounted (see FIGS. 9-10) to focus or directly align the forward flap edge 112 to the forward base edge 212 in a slidable manner. Therefore, the precise alignment between the two is no longer required, as long as the forward base edge 212 contacts an area (landing area 12) in front of the cleat edge 112 on the bottom side of the sole and the shoe edge is shown in FIG. 6A As long as the direction indicated by the arrow C moves from the base edge 212 forward, the sliding contact may be maintained. Once the forward base edge 212 slides into contact with a landing area and is defined between the edge of the cleat and the guide 116, the continuous sliding contact of the forward base edge 212 in one direction (forward direction) will be forward. The alignment and engagement of the buckle edge 112 is terminated.

7A to 7C illustrate the alignment of the rearward tab edge 114 and the rearward base edge 214. The alignment of the rearward tab edge 114 and the rearward base edge 214 is facilitated by the close fit engagement of the forward tab edge 112 and the forward base edge 212, thereby limiting the rearward tab edge 114 Rotate laterally. When the backward tab edge 114 is pushed down onto the rear base edge 214 in the direction indicated by the arrow D in FIGS. 7A and 7C, the rear tab edge 114 and the rear base edge 214 are generated. Mesh. The force exerted by the rearward tab edge 114 on the rearward base edge 214 forcibly moves the forward baseback edge 212 and the rearward base edge 214 apart from each other against the retractable bias of the spring to separate the rear Fastened to the edge 114 Engaged below the rear base edge 214.

8A to 8C show the engaged buckle and base assembly, wherein the forward base edge 212 and the rear base edge 214 and the forward buckle edge 112 and the rear buckle edge 114 are disposed in the forward direction. The gusset edge 112 and the lateral contacts 118 on the opposite sides of the rearward gusset edge 114 are in mating contact. The disengagement of the cleat assembly 100 and the base assembly 200 can be achieved by rotating the clasp assembly 100 clockwise (the heel is outward) or counterclockwise (the heel is inward). In order to facilitate the disengagement of the meshed fastener assembly 100 and the base assembly 200, the corners of the forward base edge 212 and the rear base edge 214 may be angled or inclined. The lateral contact 118 may be provided as a circular cam surface. The rotation of the cleat assembly 100 causes the cams of the inclined portions of the forward base edge 212 and the rear base edge 214 to abut against the lateral contacts 118 and resist the biasing bias of the spring mechanism (not shown) to forcibly space each other. The front base edge 212 and the rear base edge 214 are pushed forward, thereby releasing the cleat assembly 100 from the pedal assembly 200.

In a preferred embodiment, the lateral contact 118 is made of a material having a hardness measure greater than that of hardened steel. Alternatively, or in addition, the forward base edge 212 and the rearward base edge 214 are preferably made of a material different from one of the lateral contacts 118, and are preferably made of hardened steel. Preferably, the two contact surfaces (for example, the edge of the base and the lateral contacts) are made of different metal materials in order to avoid the problem of obtaining or forming a cold weld or a bonded surface between the two metals. In addition, the contact surface must have sufficient strength and durability to resist wear and tear caused by repeated engagement and disengagement.

Any of several hardness metrics, such as Mohs, Vickers, Brinell, etc., can be used to determine the relative hardness of a material relative to a hardened steel. Any material characterized as having a hardness measure greater than one of the hardened steel can be a suitable material for use in either or both of a set of contact surfaces, regardless of the measurement method. By way of example, hardened steel is generally characterized as having a Mohs hardness of about 7.0. Therefore, any material having a Mohs hardness greater than 7.0 is suitable for use in either or both of the contact surfaces.

Non-metals such as ceramics and better carbides represent one of these suitable materials. Carbides are typically characterized as having a Mohs hardness of 9 or more and containing silicon carbide, boron carbide, tungsten carbide, and titanium carbide. Carbides are preferred because they are characterized as extremely hard, non-brittle, resistant to corrosion, and resistant to adhesion to other surfaces in the presence of friction.

Therefore, in a preferred embodiment, the lateral contact 118 is a cylindrical insert made of Mohs hardness greater than 7.0 and preferably selected from silicon carbide, boron carbide, tungsten carbide and A group of non-metals or a carbide made of titanium carbide.

The general principle here is that at least one (if not both) of the two frictional contact surfaces involved in the engagement or release of the cleat assembly 100 and the pedal assembly 200 is determined by having a hardness measure greater than one of the hardened steel (for example, , A Mohs hardness greater than 7.0), preferably, a non-metal or carbide selected from the group consisting of silicon carbide, boron carbide, tungsten carbide and titanium carbide.

The frictional contact surfaces involved in the engagement of the cleat assembly 100 and the pedal assembly 200 generally include a forward base edge 212 and / or a rear base edge 214 and a lateral contact 118.
